Get answers to common questions about hvac services in Stockton, Illinois.
The ideal times are early spring (March-April) before the humid summer and early fall (September-October) before the cold winter. Stockton experiences high summer humidity and winters with temperatures often dropping below freezing, so servicing your system in these shoulder seasons ensures it's reliable when you need it most and helps you avoid the high-demand rush periods when HVAC companies are busiest.
Yes, homeowners should check for current offers from Jo-Carroll Energy, the local electric cooperative, which often provides rebates for qualifying high-efficiency heat pumps and air conditioners. Additionally, federal tax credits for energy-efficient home improvements frequently apply. A reputable local HVAC contractor will be up-to-date on all available incentives to help you maximize your savings.
The mineral-heavy hard water common in the area can lead to scale buildup in humidifier systems and boiler components, requiring regular descaling or the use of a water softener. Furthermore, for ground-source (geothermal) heat pump systems, the local clay soil properties are an important design consideration for the underground loop field, impacting installation methods and efficiency.
Prioritize local, established companies with strong community reputations, as they understand our specific climate challenges. Ensure they are fully licensed, insured, and hold appropriate Illinois EPA certification for handling refrigerants. Always ask for references from nearby homes and verify they obtain the required local permits for major installations like furnace or AC replacements.
A common rule is to consider replacement if repair costs exceed 50% of the value of a new system or if your furnace is over 15 years old. Given the severity of Stockton winters, an aging, inefficient furnace can lead to high propane or natural gas bills and risk a failure during a cold snap. A modern, high-efficiency model will provide significant fuel savings and greater reliability.
